728478 ÷ 68 
The aim is to understand the frequency of 68 in 728478.

Step 1:
7 divided by 68 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 68

Let's proceed to step 2:
68 goes into 72 1 times with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 68 away from 72, we end up with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 68

Advancing to step 3:
68 goes into 48 0 times with a remainder of 48.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 48, we end up with 48.
Append the next digit (4) from the dividend to 48 and continue with: 484 / 68

Going ahead to step 4:
When dividing 484 by 68, we get 7 with a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 107.0
If we take 476 away from 484, we end up with 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 68

Going ahead to step 5:
68 goes into 87 1 times with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1071.0
The remainder is 19 after subtracting 68 from 87.
Fetch the next digit (8) from the dividend, attach it to 19 and continue: 198 / 68

Let's proceed to step 6:
The number 68 fits into 198 2 times, leaving a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 10712.0
Subtract 136 from 198 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 7:
68 can be fit into 620 9 times, resulting in a remainder of 8.
The next digit of our result is 9. 
Result so far: 10712.9
Subtracting 612 from 620 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
80 divided by 68 is 1 with a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 10712.91
Subtracting 68 from 80 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 9:
If we divide 120 by 68, we get 1 and a remainder of 52.
Use 1 as the next digit of our solution. 
Result so far: 10712.911
Subtract 68 from 120 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 10712.911 and a remainder of 0.0052.
